“The extensive scientific research about ozone is clear: breathing it can kill you,” said Mel Peffers, air quality project manager for Environmental Defense. “Smog endangers human health at concentrations well below the current federal standard and it is especially dangerous for children, the elderly and people with asthma and other lung diseases.”
CASAC has recommended that the ozone health standard should be set in the range of 0.060 to 0.070 ppm. EPA has proposed to set the health standard within the range of 0.070-0.075 parts per million (ppm), but the agency also is soliciting comment on keeping the current standard of 0.08 ppm — which would leave millions of Americans at risk.
The
Clinical studies of healthy adults show decreased lung function, increased respiratory symptoms, inflammation, and increased susceptibility to respiratory infection at the current standard of 0.08 ppm, with one study suggesting adverse lung function effects in a sensitive subset of the population at 0.06 ppm. Short-term increases in ozone were found to increase deaths from cardiovascular and respiratory causes in a large 14-year study in 95
According to EPA, lowering the ozone health standard to <0.065 compared to ozone concentrations in 2004 (a year when weather conditions resulted in relatively low ozone concentrations) would lower the mortality rate from 15 to 6 people per one million in
Each year, pollution reductions due to effective implementation of the Clean Air Act prevent more than 200,000 premature deaths, more than 650,000 cases of chronic bronchitis, more than 200,000 hospital admissions, more than 200 million respiratory ailments, and more than 22 million lost work days. The monetary benefits to society have outweighed the costs by a factor of more than 40 to 1.
Technological innovation has made these far-reaching gains in reducing air pollution and protecting public health possible at far less cost than originally anticipated. For example, in 1994, automobile manufacturers estimated the cost of advanced low emission vehicles would be in excess of $1,500. One year later, Honda placed a Civic subcompact model on the market that emitted less than half of what was permitted under
